24h access expression

[henarmartinsantos]

Express 24h access duration as constraint (UC-12 to UC-21)

• Current approach: "P24H"^^xsd:duration

  odrl:constraint [ 
      odrl:leftOperand odrl:elapsedTime ;
      odrl:operator odrl:lteq ;  
      odrl:rightOperand "P24H"^^xsd:duration 
  ]
  

• Dynamic refinement approach (UC-16 & UC-21):

odrl:target [
            odrl:source ex:lab-test-results ; 
            odrl:refinement [
                a odrl:Constraint ;
                odrl:leftOperand ex:labTestType ;
                odrl:operator odrl:eq ;
                odrl:rightOperand loinc:2345-7 ], [ # LOINC Glucose test "2345-7" 
                odrl:leftOperand odrl:dateTime ;
                odrl:operator odrl:lteq ;
                odrl:rightOperand "P24H"^^xsd:duration ;
                odrl:rightOperandReference ex:accessToNonHCPEvent] ] ;

• Original approach:

  [
      odrl:leftOperand odrl:elapsedTime ;
      odrl:operator odrl:lteq ;  
      odrl:rightOperand [
          a time:Duration ;
          time:unitType time:unitHour ;
          time:numericDuration 24 ] 
  ]

- How does the engine know that it means P24H after the event?

[henarmartinsantos]

Should it always be added an: odrl:rightOperandReference ex:accessToNonHCPEvent
